A Study Observing Disease Progression in a Patient With Hutchinson-Gilford Progeria Syndrome (HGPS) (progeria)

September 21, 2026 updated by: MinYoung Kim, MD, PhD, Bundang CHA Hospital

A Prospective Longitudinal Observational Study of a Patient With Hutchinson-Gilford Progeria Syndrome: Establishing Natural History Data for the Development of AAV-Cas13-Based RNA-Targeting Gene Therapy

This study is a prospective, non-interventional, single-patient observational study following one patient with Hutchinson-Gilford Progeria Syndrome (HGPS), a rare disease that causes rapid, premature aging, over a 3-year period without any therapeutic intervention. The main purpose of this study is to track disease-related biomarkers over time - through physical measurements, cardiac and vascular ultrasound, bone age and bone density scans, cognitive testing, and quality-of-life assessments, along with blood tests (a total of 4 research blood draws, 3ml each) - in order to establish baseline natural history data that will support the future development and evaluation of an RNA-targeting gene therapy (based on AAV-Cas13 technology) for this condition.

Detailed Description

HGPS natural history observation cohort

Prospective, non-interventional, longitudinal follow-up of 1 genetically confirmed HGPS patient (LMNA c.1824C>T, p.G608G) over 4 timepoints (Baseline, Year 1, Year 2, Year 3, ±1 month window) Molecular biomarker profiling: progerin mRNA/protein, lamin A/C ratio, p21 (CDKN1A), endothelial dysfunction panel (ICAM-1, VCAM-1, MCP-1, eNOS), inflammatory cytokine panel (IL-1β, TNF-α, CRP, IL-6, IFN-γ), innate immunity/atherosclerosis panel (TLR4, ox-LDL, PAI-1) via RT-PCR and ELISA on PBMC and serum Cardiovascular assessment: echocardiography (diastolic function, LVEF, global longitudinal strain), carotid-femoral pulse wave velocity, carotid echodensity and intima-media thickness, ECG, ankle-brachial index Skeletal and growth assessment: anthropometry, DEXA (bone mineral density, body composition), range-of-motion measurement, whole spine X-ray Neurocognitive and functional assessment: age-appropriate IQ testing (K-WISC-V/K-WPPSI-IV), neurological exam, Progeria Severity Score, PedsQL, ADL evaluation Research blood sampling: EDTA 3ml × 4 timepoints (total 12ml)

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
